Abstract

Se proporciona una herramienta situada en el fondo de la perforacion (1) para proporcionar una fuerza de empuje a un cuerpo alargado (5) que se extiende en un pozo de sondeo formado en una formacion de tierra. La herramienta (1) comprende al menos un cuerpo giratorio (15) provisto con una pluralidad de rodillos (23), cada rodillo se expone contra la pared del pozo de sondeo a una fuerza de contacto seleccionada entre el rodillo y la pared del pozo de sondeo. Los rodillos (23) se orientan cuando se expanden contra la pared del pozo de sondeo para girar a lo largo de una trayectoria helicoidal en la pared del pozo de sondeo, y un motor (7) se provee para hacer girar cada cuerpo giratorio (15). La herramienta además comprende medios de medicion (6) para medir la fuerza de empuje provista o suministrada por la herramienta y un sistema de control (37) para controlar la fuerza de empuje provista por la herramienta (1) regulando la torsion rotativa del cuerpo giratorio, en respuesta a la fuerza de empuje medida.
